Carl Rabl (2 May 1853 in Wels, Austria – 24 December 1917 in Leipzig, Germany) was an Austrian anatomist. His most notable achievement was on the structural consistency of chromosomes during the cell cycle. In 1885 he published that chromosomes do not lose their identity, even though they are no longer visible through the microscope.As a student, his influences included Rudolf Leuckart at Leipzig, Ernst Wilhelm von Brücke at Vienna and Ernst Haeckel at the University of Jena.
